We strongly recommend ordering the sizing kit or visiting our “Getting the Right Fit” page to ensure accurate measurements for your chastity device.

Please contact us if you need to request a refund.

Any of our devices can be comfortably worn by uncircumcised individuals. We have found that inverting the bars on the front of the cage is beneficial, as it pushes clothing away from the end and prevents pinching.

To request this customization, please include the note ‘INVERT FRONT BARS’ in the comments section of the online order form.

All of our cages are custom-tailored, which means each one can be crafted to fit a range of sizes, no matter how small or large. To ensure a perfect fit, it’s essential to provide accurate measurements. If you have any questions or need assistance in selecting a model or providing measurements, please feel free to contact us.

We’ve had customers employ a ring with an attached cable or chain that locks onto the device as a means to prevent pullout. Additionally, we can modify the device by removing the center portion of the lower horizontal bar. This alteration allows a capture ring to protrude, enabling you to secure it. Feel free to contact us for more details or customization requests.

No, we don’t offer hinged bases for “A” rings/base rings, which are types of rings that can be part of a chastity device. We’ve found that these kinds of rings tend to cause irritation and chafing. Instead, all of our devices are designed for comfort during continuous wear. Our customers frequently prefer the oval ring design, as it contours more naturally to the body, making it so comfortable that they often forget they are even wearing the device.

We apologize, but currently, we do not offer a Prince Albert attachment. We have been working to developing one, but it has proven challenging to meet our high standards for comfort and weight. We are committed to ensuring that any product we offer provides the utmost in comfort and quality, and at present, we have not been able to achieve this with a Prince Albert attachment.

Yes, the Punishment Pins are designed to cause discomfort. We don’t call them Punishment Pins for nothin! They are available in three sizes: Small, Medium, and Large. The level of discomfort varies depending on the size of the pin chosen. The Small pin is the least intense, while the Large pin offers the most pronounced sensation. It’s important to choose the size that aligns with your preferences and comfort thresholds.

Mature Metal LLC. has one goal in and that is to build the most comfortable and best looking custom chastity devices on the market. We cannot obtain that goal unless we give the highest standards in customer service. Words we live by are “The sale is not over until the customer is happy”. We do know and understand that things can go wrong, and that is why we make every effort to make the best of any situation.
